This t-shirt is super easy to wear. You can pair it with jeans for a casual look or layer it under a blazer for a more dressed - up style. When it comes to washing, it's best to use cold water and a gentle cycle to keep the colors and fabric in good condition. Avoid using bleach as it may damage the cotton and acetate blend. After washing, you can tumble dry on low or hang it to dry. As for sizing, remember it's Asian Size, so you may need to order a size or two larger than your usual US/UK/EU size. And because of the manual measurements, expect a small difference in the actual size. Enjoy wearing your new turtleneck t-shirt!
